Manual Ball Valve
Introduction：
The opening and closing member (ball) is driven by the valve stem, and the manual ball valve is a valve that rotates around the axis of the ball valve. It can also be used for fluid regulation and control. Among them, the hard-sealed V-flange ball valve has a strong shear force between the V-shaped ball core and the metal valve seat of hard alloy surfacing, which is especially suitable for fibers and tiny solids. particles, etc.
Features:
1. Open and close without friction. This function solves the problem that the sealing of traditional valves is affected by friction between the sealing surfaces.
2. Top-loading structure. The valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce the shutdown of the device and reduce the cost.
3. Single valve seat design. It eliminates the problem that the medium in the cavity of the valve affects the safety of use due to abnormal pressure increase.
4. Low torque design. The valve stem with special structure design can easily open and close the valve with only a small handle.
5. Wedge-shaped sealing structure. The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat to seal, so that the sealing performance of the valve is not affected by the change of pipeline pressure difference, and the sealing performance is reliably guaranteed under various working conditions.
6. Self-cleaning structure of sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline passes 360° evenly along the sealing surface of the ball, which not only eliminates the local scouring of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning .
